The performance of the FAV detector can be optimized by adjusting the parameters found in the [fav.json](detectors/fav.json)

The OBI (Octave Band Intensity) detector, on the other hand, detects boats by looking for variations in the
sound intensity within the 2nd, 3rd, and 4th octave band, centered at 125 Hz, 250 Hz, and 500Hz.

Below, you see the spectrogram of a 10-second long audio recordering containing noise from a boat.
